TIME-KEEPING DEVICE.

Application filed November 10, 1911.

T 0 all whom it may concern Be it known that I, CARL C. HARRIS, acitizen of the United States, residing at Orange, in the county ofFranklin and State of Massachusetts, have invented a new and usefulTime-Keeping Device, of which the following is a specification.

The principal objects of this invention are to meet the demand for atime keeper which can be used readily by workmen in place of theexpensive clock operated instruments now largely employed; also toprovide simple means whereby a workman can quickly and easily make apermanent record of the time of beginning and finishing any work, andwhich shall take away from the workmen the privilege of recording theirtime at will.

The invention also has for its objects to provide a device of thischaracter in which no mental effort will be required on the part of theworkmen to record the beginning and stopping time on any particularpiece of work; to provide a construction in which the workmen shall notbe required to leave the usual place of work at bench or machine inorder to record their time; to provide a construction in which thinpaper or cardboard time slips can be used practically and can be kept insuch a way that they are always ready for immediate inspection by theforeman in charge; to provide a device of this character with a visibleand constant check for the foreman always showing the time that anyparticular job was started or the time at which the workman commencedwork; to provide time slips or tickets which are unchangeable and cannotbe altered readily by the workmen; to provide a construction which alsoallows more accurate data in connection with piece-work and daywork byreason of the fact that it is practical to have additional time slips onwhich to record special operations if required; to provide aconstruction of time keeper particularly valuable when several of themare used for several different machines operated by the same man, sothat in such a case each man may record on each time keeper separatelyand independently of the others thereby keeping definite records of thework on each separate machine or job under his charge; to provide aconstruction which shall be entirely flexible as regards use, that is,one which can be used by a few men in a Specification of Letters Patent.

strument of this kind in which the lunch K or noon hour is automaticallytaken out from the total; to provide a construction in which the case isof very simple character and serves as'a holder for active order slips,and also future work ahead of the workmen; to provide a simple manner ofeffectually holding the time slips in position; and to provide anexceedingly simple form of device for marking the time slips.

Reference is to be had to the accompanying drawings in which Figure l isa front elevation of a time keeping and recording device constructed inaccordance with this invention with a time slip in position; Fig. 2 .isa front view of one of the time slips removed from the casing; Fig. 3 isa vertical sectional view on the line 33 of Fig. 1 of the entire casingshowing the hand or pointer and illustrating in elevation the means forholding the time slip in position; and Fig. l is a front elevation ofthe back of.the case.

The invention is shown in a simple form in which it comprises a sheetmetal casing 10 having on the front a clock dial 11. This clock dial orface shown is of the usual form having all of the twelve numeralsrepresenting the twelve hours spaced equally around the same, and havingthe spaces between the hour numerals divided up to indicate quarters ofan hour, and each quarter also divided into thirds to indicate periodsof time of five minutes. Concentric with the dial is a circular slot 12.This slot is not continuous all the way around, but is discontinued attwo places 13 and lt, one object being to provide for supporting it fromthe material of the case. Another object will appear below. For thepurpose of holding time slips a, the casing is provided. with a pocketjust behind the clock dial formed by a sheet metal partition 15 andhaving a space in front of it. This space extends down to the bottom ofthe casing and the partition is provided with a circular slot 16registering in all respects with the slot 12 on the clock dial. As thereis only a small space between these two plates which constitute thispartition and the front of the casing, it will be seen that the timeslip is held in such position that pressure brought to bear on itthrough the slot 12 will easily puncture it and produce an indeliblemark.

On the time card a is a circular space an adapted to register with thecircular slot. This space is continuous. Adjacent to this space is ascale a of hour divisions similar to the hour divisions on the clockdial, but the Zero division is located to register with the opening hourof the works as for example in this case VII. These divisions arenumbered in regular order up to the one which corresponds with the XIInumeral on the dial or such other position as indicates the closing forthe lunch hour. Then there is a space to the opening hour after thelunch hour, for example, the I numeral on the clock dial. The numeral(as for example 5 on the drawing) which registers with the XII numeralon the clock dial is repeated at this point, then the numberingcontinues on until the closing hour. In this way it will be seen thatthe number of hours registered on the time slip can be computed veryeasily. In case the operative commences at 7 oclock, there will be noreal computation at all as the number of hours he works during the daycan be read directly on the time slip. It will be seen that the timelost during the lunch hour is taken out automatically on account of therepetition of the numeral at XII and I. The spaces between the numerals011 the time slip representing the hours are not divided into quartersand minutes, but into tenths of an hour. This also facilitates thecomputations in a way that will be obvious. The time card is also shownas provided with a clock dial a exactly similar to the clock dial 011the casing, except for size, so that in computing the time of theoperative the computer will at all times be able to see exactly what thedifferent divisions on the scale a represent on the clock dial. Thistime slip is provided with a dot a at the center of the circular scalewhich must register with the center of the clock dial. For this purposethe clock dial has a central perforation 17 through which this dot maybe observed. The time slip will be provided with such heading spaces asare desired, a convenient form for certain classes of work being shownin the drawings.

In order to hold the time slip perfectly in position the rear wall ofthe casing is shown as provided with integral springs 18 punchedtherefrom, each having a spur 18 on the end. These springs rest oneccentric portions 19 of a rock-shaft 20 located in the casing. Thisshaft has a handle 21 projecting from one end by which it is operated.It is mounted in bearings 22 integral with the casing. It will beobvious that when this shaft is turned to one position the spurs will beprojecting up through openings 23 the extra time slips.

in the plate 15 to perforate the time slip and to hold it in position.To receive these spurs the face of the casing is shown as provided withperforations 24L.

It will be seen that there is a pocket 25 behind the plate 15 which isdesigned to hold Its bottom is defined by transverse projections 26 inthe casing. The casing has an extension 27 projecting up at the rear sothat it can be hung conveniently on the wall or elsewhere. It isprovided with a convex surface 28 at the top to hold the cards out sothat they may be separated from each other very easily.

Concentric with the clock dial is an eyelet 30 adapted to turn on thecenter of the clock dial as an axis. On this is mounted by an integralring 31 a hand or pointer 32 arranged radially. Before being put on thisring is distorted so that it will exert a constant spring pressure onthe casing and will always be operated at about the same turningpressure. Extending along this hand or pointer is a spring 33 which hasa needle point 34: integrally connected with its end and extending downthrough an opening 35 in the hand in registration with the circularslot. The spring normally holds the needle point above the surface ofthe clock dial but an indicator 36, mounted to slide on the handle has apassage 37 at the bottom which, when the indicator is forced out,positively forces the needle point through the two slots in the clockdial and plate at the rear. This obviously results in perforating thetime slip and also prevents the moving of the pointer without mutilatingthe time slip when the indicator is in this position. Nhen the indicatoris drawn back into contact with the ring it allows the spring to forcethe needle point back, which allows the hand to be turned. As theindicator preferably is of a bright appearance and is located just abovethe surface of the clock dial which is of a dark or dull appearance, itis readily observable at a distance, and consequently it cannot betampered with without showing the fact. Ordinarily, the operative isexpected to force this indicator out to show when his work commences andnot to move it again until he leaves the works permanently or finishesthe job, then he draws it back, turns the pointer the necessarydistance, and then moves the indicator out to perforate the paper. Ifthe indicator is in the out position the needle point must necessarilyindicate on the time slip underneath and it would be diflicult, if notimpossible, for the workman to prevent the perforating needle fromrecording on the time slip when the indicator is in this position.
